Safety status
What this means for your dog
Dogs that taste-test showy fleabane usually get nothing worse than a brief stomach ache. ASPCA labels the fleabane genus as toxic because of irritant compounds, but the most common outcome in dogs is mild vomiting or diarrhea, sometimes with skin irritation if they rolled in a patch.
What to watch for
Most common: vomiting and loose stool, usually mild. Possible: drooling, a few hours of lethargy, or red itchy skin where the dog made contact. Watch for repeated vomiting that prevents holding down water.
Time window
Exact timing isn't well documented for Erigeron speciosus. ASPCA describes the signs as mild gastrointestinal effects, which typically appear within an hour or two and resolve as the irritant passes.
When to call the vet
Call your vet or ASPCA Poison Control (888-426-4435) if vomiting or diarrhea continues past a few hours, your dog can't keep water down, or you see weakness, refusal to eat, or signs of dehydration.
